Mark Sanchez has entered this season facing his most serious quarterback battle to date. His competition, Geno Smith, is an athletic second-round pick who is learning the offense quickly.

According to Rex Ryan, the two have swapped days working with the first-string offense. Sanchez, who went 8-of-11 in team drills today, was with the No. 1's today.

But Sanchez doesn't seem to be worried in the least. When asked about the possibility of not starting, he was adamant. This wasn't a possibility.

"I don't plan on that happening," Sanchez said.

Sanchez called it his best offseason to date, and amid reports that his accuracy has been better, it seems his confidence has improved from a rock-bottom in 2012.

"At that position confidence is huge," Rex Ryan said. "I think there's only one other position you better be as confident as the quarterback -- maybe more than one, kicker and cornerback -- that if you're short on confidence you're going to struggle. But I feel, really, all the quarterbacks we have are confident guys."

He admitted that Sanchez may have been lacking in that department last year.

“I think it’s safe to say maybe some of his confidence was shaken a little bit last year,” he said.
